【考案の詳細な説明】
本考案はし尿浄化槽等の汚水浄化装置に関し、特に浄化
槽の沈澱室下部における槽壁の改良に関する。[Detailed Description of the Invention] The present invention relates to a sewage purification device such as a human waste septic tank, and particularly relates to an improvement of the tank wall in the lower part of the settling chamber of the septic tank.
従来のし尿浄化槽は、その−例として、ばつ気室内底部
に設けた散気管からの上昇気泡流による旋回流に沿って
隔壁が設けられ、この隔壁によってばつ気室と沈澱室と
に区分されているが、ばつ気室内の旋回流の影響を受け
て沈澱室下部の汚水が攪乱される。For example, in a conventional human waste septic tank, a partition wall is provided along the swirling flow caused by an upward bubble flow from an aeration pipe installed at the bottom of the aeration chamber, and this partition wall divides the tank into an aeration chamber and a settling chamber. However, the sewage in the lower part of the settling chamber is disturbed due to the influence of the swirling flow in the aeration chamber.
この結果、沈澱室内に上昇流が起り、拡散気泡によって
汚泥界面が吹きあげられたり、汚泥と上澄液との境界面
が上昇して沈澱室内有効分の占める率が減少する。As a result, an upward flow occurs in the settling chamber, and the sludge interface is blown up by the diffusion bubbles, and the interface between the sludge and the supernatant liquid rises, reducing the proportion of effective content in the settling chamber.
このため、沈澱室内の汚泥沈降が悪く、ばつ気室内への
汚泥返送が不良となり、充分に浄化されないままの上澄
液が消毒室を経て槽外へ排出されたり、沈澱室水面のス
カム発生が増加して槽外へ流出し、浄化能力が低下する
原因となるなどの欠点があった。As a result, sludge settling in the settling chamber is poor, sludge return to the aeration chamber is poor, and supernatant liquid that has not been sufficiently purified is discharged to the outside of the tank through the disinfection chamber, and scum is generated on the water surface of the settling chamber. There was a drawback that the amount of water increased and flowed out of the tank, causing a decrease in purification ability.
本考案は上記欠点を除き、ばつ気室の旋回流による沈澱
室下部における汚水の攪乱を防止し、汚泥が沈澱室内へ
逆流することなくばつ気室ヘスムーズに返送されるよう
機能の良好な汚水浄化装置を提供することを目的とする
。The present invention eliminates the above-mentioned drawbacks, prevents the disturbance of sewage in the lower part of the settling chamber due to the swirling flow in the aeration chamber, and provides a sewage purification system with good functionality so that the sludge is smoothly returned to the aeration chamber without backflowing into the settling chamber. The purpose is to provide equipment.
以下本考案の一実施例を図面にもとづいて説明する。An embodiment of the present invention will be described below based on the drawings.

一方、沈澱室Ｂの隔壁２に対向する側壁下部５の傾斜角
Ｑは約６０°（それ以上でもよい）に設定されている。On the other hand, the inclination angle Q of the lower side wall 5 facing the partition wall 2 of the precipitation chamber B is set to about 60° (or more).

が逆流するのを防止するいわゆる汚泥返しの役目をする
。Since the gap between the lower part of the inclined outer wall 5 and the partition wall straightening section 21 is narrow, the protrusion 51 and the straightening section 21 adjust the water flow from the air chamber A to the settling chamber B, and the sludge flows from the bottom to the top of the settling chamber B. It acts as a so-called sludge returner to prevent sludge from flowing back.
また、整流部２１は、沈澱室Ｂ内下部の沈澱汚泥をばつ
気室ヘスムーズに吸引誘導するのに役立つ。Further, the rectifier 21 serves to smoothly suction and guide the settled sludge in the lower part of the settling chamber B to the aeration chamber.
そして、これらの単独または組合せにより沈澱室Ｂ内下

沈澱室Ｂでは汚水が静止状態に保持されることによって
汚泥の沈降分離が行われ、流入管６よりの汚水流入によ
る水位の上昇につれて上澄液が越流堰（図示省略）を経
て消毒室Ｃに入り薬剤筒９の消毒剤によって滅菌され、
流出管７より清浄水として排出される。In the sedimentation chamber B, the sludge is kept stationary to separate the sludge, and as the water level rises due to the inflow of the sewage from the inflow pipe 6, the supernatant liquid passes through an overflow weir (not shown) and enters the disinfection chamber C. It is sterilized by the disinfectant in the medicine barrel 9,
The water is discharged from the outflow pipe 7 as clean water.
ここで沈澱室Ｂ内の重い汚泥は下部に沈積し、前記突条

される。As described above, the present invention provides a rectifying section and a snow-like cutout at the bottom of the partition wall, so that the flow along the partition wall inside the ventilation chamber is uniform.
The mixed flow is not blocked from flowing into the aeration chamber, and the sludge is suctioned and smoothly returned to the aeration chamber.
従って、沈澱室内の汚泥の攪乱が減じ、汚泥層の高さを
下げることによって浄化効率が大幅に向上した。Therefore, the disturbance of the sludge in the settling chamber was reduced, and the purification efficiency was significantly improved by lowering the height of the sludge layer.

浄度は常に良好に保たれることとなった。Moreover, since the lower part of the side wall of the tank body is provided with protrusions along the width direction, the sludge that has settled in the lower part of the settling chamber does not easily fly up even when subjected to wave motion, and the supernatant liquid is purified. The temperature was always maintained at a good level.
